The plan calls for installing traffic signals above eastbound Interstate 70 on the west side of the tunnel that will cycle every 4 to 8 seconds so that vehicles only stop briefly before entering the tunnel.

If the tests are successful, the Colorado Department of Transportation will use the system during the holidays and beyond.
